Description:
A hollow spherical ball has an Absolute Pressure gauge mounted on it. Heating with boiling water and cooling with ice water causes pressure changes. Absolute zero can be extrapolated by plotting P vs. T and using measure the pressure in Boiling Water, Ice Water, and an Alcohol and Dry Ice mixture (-80C). Plot the data and the Linear line intersects x axis around -270.
